but can be easily detached and pushed down; despite this it is guaranteed that the railing cannot accidentally be advanced by an uncontrolled movement of the patient.

In addition, a bed railing is to be created, which is either adjusted as a whole or partially lowered, while the other part of the railing stays up.

There now follows a description of an embodiment of the invention with reference to the drawings.

Figure 1 is a side elevation of an embodiment of the invention used for a wheeled stretcher the railing in the upper position by solid lines and in the lower position by dash-dotted lines Lines is shown.

Firur 7 is a side elevation of one with a railing provided hospital bed, the railing in the upper position by solid lines and in the other possible Positions is shown by dash-dotted lines.

FIG. 8 is an enlarged section taken along line 8-8 of FIG.

FIG. 9 is an enlarged section approximately along the line 9-9 from FIG.

FIG. 10 is a section along line 10-10 of FIG.

FIG. 11 is a section along the line 11-11 from FIG . 6.

In Figure 1, a conventional wheeled stretcher 10 is shown. It has lateral longitudinal bars A square tube 14 suitably fastened to these extends transversely to the side rods 12, at both ends thereof inverted U-shaped parts 16 sit with disks 18 which form part of the rotating device for the railing. The parts 16 contain slots 20 in which pins 22 sit which are attached to the tube 14 and which allow a suitable adjustment of the Allow parts 16 in the tube 14 and thus a suitable position of the railing in relation to the bed.

A railing 24 of suitable shape is at 26 with a Linkage 28 rotatably connected. The lower end of the linkage 28 includes a pivot 30 which extends through a vertical longitudinal opening 32 in the disk 18

which is attached to the inverted U-shaped part 16 is. Concentrically around the pivot 30, a ring element is provided which contains mutually separate slots 36, into which a latching part 38 can engage, which extends radially from the edge of the disk 16, as in FIGS. 3 and 5 As shown, the cage or insert formed by ring member 34 has an inner diameter slightly larger than is the distance from the lower edge of the disc 18 to the outer edge of the locking part 36, so that the rotary linkage 28 and through the ring part 34 formed cage around the disc 18 and around the locking part 38 can be rotated when the locking part in none of the locking slots 36 engage.

In FIGS. 2 and 3, the connecting rods 28 are in a vertical position, the latching part 38 being latched in the upper base 36. In this way, the railing 24 is held in a vertical position, as shown in FIG. 1, and offers stability in the lateral direction from the bed of the patient to the outside. To lower the railing, it is raised so that the bast parts 36 on both connecting rods disengage from the slots 36} then the railing can be pivoted clockwise or counterclockwise near the bottom. A clockwise direction of rotation Ib is shown in FIG. 5, but the opposite direction is also possible. If the railing and the rod Verbindungege- '28 have been rotated from the upper position by 180 ° downwards, engages the latching portion 38 in the slot gegenüberliegtnätn

one that is then on top, taking the weight of the railing the locking part holds in the slot so that when the stretcher 10 moves, the railing does not become undesirable Way moves.

In FIGS. 7, 8 and 9, the railing is shown for use on a hospital bed 40. A railing 42 is rotatably connected to connecting rods 44, as in a similar manner to the above for connecting rods 28 has been described. The lower end of each connecting rod 44 has a cage 46 formed by an annular part, which is similar to the annular member 34 from the first embodiment. The lower end of each connecting rod 44 has a pivot 48 which corresponds to the pivot 30 of the first embodiment. A disc 68 and locking parts 69, corresponding to the disk 18 and the locking parts 38 are shown in FIG. 11, the spacer part 67 being the disk 68 with a leg 50 connects. The lower ends of the legs 50 are provided with a clamping device which is generally is denoted by 52. This clamping device contains lugs 54 and two attached below at a certain distance and with Internally threaded bushings 56 which are welded to rods 58 or otherwise suitably attached. These rods 58 can be pushed into a central tube 60, which is provided with set screws for locking the rods 58. Sit in the internally threaded sockets 56 Screw bolts 64 on which the bed frame 66 with its lower

side rests, the lugs 54 on top of the; Bed frames rest.

As shown in Figure 7, the railing 42 (and also the railing 24 of Figure 1) can be in a through the be moved diagonal position shown by dash-dotted lines. This inclination may then be necessary if the nursing staff is to treat the patient at the head or foot end, using the above section of the handrail ensures that a restless patient does not completely or partially roll off the bed. Purely the inclination from Figure 7 the railing can be rotated clockwise from the upper position shown in solid lines until the Connecting bars 44 lie horizontally. Then the right end of the railing, as can be seen from Figure 7, is down and move the left end up. The railing can also be seen in the diagonal opposite to FIG. 7 be placed at an angle if so desired. It should be mentioned that the railing, if you only have a connecting rod is still firmly anchored. To lower the railing, both connection points must 28 be lifted.

From the above description it can be seen that a railing for stretchers or beds has been created which is attached so that it can be pivoted downwardly from the upper position in a gentle movement, the railing in both positions against a random ^v * ^ schi.e ¹ '^ secured

is. The movement process is smooth and easy, and the The construction has the advantage that the movement process is neither disturbed by the bedding, nor does it bring it into disorder, A lock does not have to be opened by hand but The railing can only be lifted slightly to release the east parts from the slots. A nurse or something else Nursing staff can operate the railing with one hand if it is grasped at the top, approximately in the middle.

Obviously, various modifications may be made in terms of details, arrangement and mutual relationship the items are made to each other, insofar as they fall within the scope of the invention.
